Story Highlights
With 40,000 fans onsite watching five live esports stages and four content stages sprawled across a million square feet at Anaheim Convention Center, it simply doesn't get any bigger for the Blizzard Entertainment production operation than BlizzCon. In addition, Blizzard's Global Broadcast team is distributing a whopping 211 unique broadcast streams to 17 outlets in 18 languages.
This weekend, 40,000+ fans will descend upon the Anaheim convention center for BlizzCon.
For us, the live event and the broadcasts are very linked together because so much of the broadcast is from these live stages. Our show is definitely bigger this year, says Pete Emminger, senior director, Blizzard Entertainment. We're really lucky in that we have a lot of consistent crew, so this year has actually been the smoothest year so far. Plus, we've really had a great year at Blizzard overall, so we're extremely excited to finally be here at BlizzCon, which is really a celebration for us as much as it is [for the fans].
A Blizzard of Activity: A Dozen Mobile Units Onsite Serving Nine Stages
Now in its 14th year, the convention features everything from live esports competitions to Q&A panels and announcements to demos of upcoming game releases to concerts and much more.
The Overwatch World Cup stage is handled by NEP's HDR-capable ND6 mobile unit
Blizzard's Global Broadcast team has a dozen mobile units (including A and B units) and two flypacks onsite to serve the cavalcade of stages in Anaheim - with all shows feeding into a central Master Control and a new Post Hub operation.
The way we have it set up, every content stage and esports stage is a separate production unit, says Emminger. All of that comes together in our Master Control at BlizzCon, which [handles] routing and distribution of live signals between all of the stages.
Blizzard has deployed a dozen mobile units (including A and B trucks) at BlizzCon this year.
BlizzCon's five esports stages are Hearthstone (handled by Lyon Video Lyon 11), Heroes of the Storm (Clark Media's 4K-capable Goliath), the Overwatch World Cup (NEP's HDR-capable ND6 for the main production and BT-1 for the observer room), StarCraft II (NEP's 4K-capable Atlas A and B units), and World of Warcraft (NEP TS2 A and B).
Of the four content stages, Mythic Stage (the main stage ) is handled by NEP's Denali Gold A and ST-79 and All Access Channel is produced out of by Dome 4K with a B unit. Legendary and Epic Stages are produced via flypack because of their location on the second floor of the convention center.
All feeds lead to the master-control operation, which is built around an Imagine Communications Platinum router (200 176, eight multiviewers) with 40 AJA FS2 frame sync/converters. A Ross Video Ultrix router (128 128) feeds the Spider X80 multiviewer video processer and seven LED destinations. In addition, 10 media servers feed all the LED elements and programs, and nine discrete IPTV channels (using Exterity) are distributed to LED walls throughout the convention center so that fans can watch stages from wherever they are. Master control also features a DiGiCo SD10 audio console (64 24).
In addition to [routing and signal distribution for the stages], Master Control is [managing] all of our broadcasts, says Emminger. So we do final QC work on audio and lighting there, as well as all of our transmission operations. And then we have all of our key platform partners -both internal like BlizzCon.com and external like Twitch - with us in Master Control. That way, everything from a signal acquisition and an output perspective can all be managed from one place.
Debut of Post Hub: Postproduction Centralized in Anaheim
The most significant new addition from an infrastructure standpoint this year is the debut of a Post Hub operation.
The StarCraft stage at BlizzCon
[In the past], all the different stages did all their own post, and we actually still had PAs running drives between all these trucks, says Emminger. So, this year, we knew we needed to build a dedicated Post Hub.
Blizzard brought in a colossal 500-TB OpenDrives NAS for the edit/post team to fill throughout the weekend (although Emminger expects it to be roughly two-thirds full by weekend's end). The NAS is broken into two: an SSD NAS for edit and hybrid Grass Valley K2 Summit NAS for archive. Records are all done via EVS XT3 and IPDirector with EVS operators clipping from a total of 30 channels via seven trucks. The Post Hub operation comprises eight editors, two EVS operators, five MAM ops, and three CMS ops (which manage all content to BlizzCon.com).
We realize 500 TB is pretty substantial for a single weekend show, says Emminger. But, considering the amount of [content] we create at BlizzCon, we felt it was appropriate.
Inside the Convention Center: A Feast for the Eyes
With nine stages and a host of other activities, it's no surprise that Blizzard's camera complement is massive, comprising more than 50 broadcast cameras (a mix of Sony HDC-4300's, Grass Valley LDX86's, and Sony HDC-2500's), six robos, and a multitude of miniature POV cameras (primarily Blackmagic Design 4K MicroUltra and Marshall 3G systems) deployed across the various stages.
Blizzard All Access serves as the news-focused studio show at the BlizzCon.
Our All Access channel is a fairly static news-focused show, notes Emminger. It has a few monitors in the set in the background, but it's really intended to focus on the content itself. That's where we do most of our key interviews.
